Congratulation for you to find this execting project. Let's make a GPS jammer for cars steps by steps.
- Prepare the RF (Radio Frequency) Signal Generator
This is the core component of the GPS blocker. The signal generator emits radio frequencies to interfere with GPS signals.
For civilian GPS systems, the common frequency is 1575.42 MHz (L1), but the blocker might also target other satellite navigation frequencies such as GLONASS or Galileo.
-
Install the amplifier
The amplifier can boost the strength of the RF signals generated by the signal generator, allowing the blocker to operate over a range of 3 to 10 meters.
- Install the antenna
The antenna can broadcast the interference signal. The type of antenna used determines the range and coverage of the jammer.
- Power Supply Connection
Attach the 9-volt battery to the breadboard, ensuring that the positive and negative terminals are connected correctly to the power rails.
- Integrate the GPS Receiver Module
Finally, connect the GPS receiver module and antenna to the circuit. This will allow you to homemade GPS jammer test the effectiveness once the circuit is complete.
- LED Indicator or Display
Some GPS blockers include an LED light or small display to show the status of the device.
